What do you mean by Latent heat of evaporation! (not vaporisation/fusion) Kindly tell from Science NCERT class 9.
(Indian NCERT)!

Respuesta :

Since none answered from Indian NCERT yet, let me give a simple definition from ICSE..
Latent Heat of vapourisation is the heat energy required to convert unit mass of a substance from liquid to vapour state WITHOUT ANY CHANGE IN ITS TEMPERATURE.... 
hope this helps!
